Anyone who suffers from sinus infections, respiratory infections or live in a dry climate, might want to take some time out of their busy day and invest in a cool-mist humidifier. If the humidity level inside of your home isn’t correct, then it can result in an increased incidence of sinus infections, colds, and allergies. Dry air can also cause chapped lips, skin conditions, and other serious disorders. That’s why buying the best cool mist humidifier should be high up on anyone’s list. We’ve looked at several of these models, and we’ve reviewed the ones that we think are the best at what they do. Let’s take a closer look at them and check out their features.

Quick Summary of the Best Cool Mist Humidifiers

Best Overall: Dreamegg Cool Mist Humidifier

This cool-mist humidifier is the perfect one for just about any home. It’s designed to be used with large rooms and is especially useful in bedrooms. This unit has a 4.5-liter (1.2-gallon) capacity, so it can run for up to 45-hours at a time when it’s used on the lowest setting. That allows the user to fill it up and run it and not have to worry about refilling it after every single night.

Another thing worth mentioning about this humidifier is that it only produces about 32-decibels of sound while it’s running. That’s quieter than the average whisper. This makes it perfect for use in the bedrooms of both children and adults alike.

It’s also worth noting that this product also has several great features that make it quite easy to use. Our favorite feature is its night light mode, which can be turned off if the user so desires. Another feature that it has is its smart auto-off timer. This timer can be set for 2,4 or 8 hours and will automatically turn the unit off.

The center of the unit is also easy to remove, so it can be easily emptied or refilled. And since it has a big handle, it can be carried to and from the sink with ease. And probably best of all, this unit uses very little electricity, so the consumer doesn’t have to worry about it running up their electric bill.

One of the best features worth mentioning, however, is this unit’s nightlight. It can be turned on and dimmed, or turned off entirely if the user doesn’t want to have it lit at night. That makes it a great addition to any children’s bedroom and something a lot better than just turning on the hallway light and cracking the door to use as a nightlight.

And because this unit’s buttons are touch-activated, the consumer can easily use the cool mist humidifier, even in an entirely dark room. All of these features make this product one of the best cool mist humidifiers around.

A lot of people would love to have a cool-mist humidifier in their room for use while they’re sleeping, but they may feel that there isn’t a model that’s both effective and quiet. Fortunately, we’re able to solve that problem by recommending this cool mist humidifier. This model is not only extremely effective at adding moisture to the air, but it’s also extremely quiet.

The average whisper comes in at a decibel level of 30dB, but this humidifier is only 26dB. It’s so quiet, some people may not even notice it while they’re sleeping. And who wouldn’t want a model that was that whisper-quiet?

This model features a 6-liter tank, which is 1.6-gallon of water, and that’s enough for this product to provide a cool mist for anywhere from 20-hours to 60-hours–all depending, of course, on the humidifier’s setting. When this model is placed in a room that’s anywhere from 215 to 430 square feet, it will do a marvelous job of adding humidity to the air.

And because it has an optional nightlight, this model is also appropriate for use in children’s rooms. If the consumer doesn’t want the nightlight feature to be on, then all they have to do is turn it off.

If there was any problem we had with this humidifier, it was the fact that it was difficult to refill. Sure, it does have a 90mm water inlet that’s supposed to make it easier to fill, and it does while it’s under the faucet. But then comes the time when the consumer has to carry that heavy 1.6-gallon tank to their humidifier and that’s when a lot of people are going to have problems.

When the tank is filled, it’s just not very light. Some people might not think that it’s a big deal, but for us, it did matter. Only the consumer can determine if this is a dealbreaker or not when they’re considering this product.

What we liked about it
This unit works very well.
This model is extremely quiet.

Also Consider: Levoit Bedroom Ultrasonic Humidifier

The Levoit Humidifier is another product that’s made for use in bedrooms. It only produces about 30-decibels of sound or about as much sound as a whisper from across the room. It’s capable of performing this quite impressive feat because it’s equipped with a patented silencer that helps to keep its sound levels down and do it without interfering with its operation.

And another thing that makes it great for use in the bedroom is that it has a blue night light on it. This can be used to comfort children when they’re going to bed, or if the user prefers total darkness, it can also be turned off.

This model features a 0.63-gallon water tank, which is approximately 2.4-liters, and it has a 250 ml/hour output. This means that it can provide about 24-hours of cool mist when it’s on its lowest setting. That makes it quite effective for rooms that are 290 square feet or smaller in size, but it’s not very effective for larger rooms.

Another thing worth mentioning is this product is 8.5×6.7×10.2-inches in size, so it’s the perfect size to be placed on most bedside tables or chest-of-drawers. And because it’s equipped with a detachable power cord, it’s easy to take from one room to the next.

Other features that can be found on this nice humidifier include a 360-degree mist nozzle, three different mist levels, and ultrasonic technology that adds moisture to the air without soaking down walls, furniture, or floors. It’s also0 equipped with an automatic safety shutoff that turns the unit off when it’s run out of water.

And because the refillable tank is BPA-free, consumers also don’t have to worry about harmful chemicals that can be found in other plastics. That makes it a great choice for nurseries or children’s rooms and a great addition to any home.

What we liked about it
This product is very safe and reliable.
This unit works well.

In this guide, we’re going to go over some of the features that the consumer should consider when buying one of these humidifiers and how to select one that will fit your needs. Before we start with that, however, let’s begin by talking about some of the benefits of using a cool-mist humidifier in your home.

The Benefits Of Using A Cool Mist Humidifier

Anyone who has wondered why using a cool-mist humidifier in the home is a good idea is going to want to read this section of this guide. Although we could be snarky and say that the main benefit of using these products is to add humidity to the air, the real question people are asking when they’re wondering the purpose of these products is what the benefits of increasing the home’s humidity in the first place. And there are quite a few benefits of raising the humidity in the home, so let’s take a look at some of them to see why buying a cool-mist humidifier is a good idea. 

The Benefits Of Increased Household Humidity:

  • Relief for sore throats, itchy eyes, and noses.
  • Relief for dry skin.
  • It helps to alleviate snoring.
  • Helps with nose bleeds.
  • It helps prevent sinus infections.
  • Better for people with respiratory conditions. 

Choosing A Cool Mist Humidifier

Okay, let’s get started and talk about some of the features that you should think about before you choose your next humidifier. Below are some of the things that all consumers are going to want to consider before they settle on a humidifier for their home. 

Evaporative Or Ultrasonic Humidifiers

The first thing that consumers are going to need to think about when buying a new humidifier is whether they want an evaporative humidifier or an ultrasonic humidifier. Since both of these models have their pros, as well as their cons, the consumer is going to want to weigh their needs against the benefits that these products provide to choose one appropriate for them. 

Evaporative Cool Mist Humidifiers

These humidifiers are the ones that are most commonly purchased nowadays. That’s because they don’t cost a whole lot of money, and were among some of the first humidifiers to hit the market. They work by using some sort of wick that absorbs the water and then that moisture is transferred to the air coming out of it. Let’s take a closer look at the pros and cons of this product. 


  • They’re not very expensive
  • They work very well
  • They can add humidity to large rooms


  • They can be loud
  • They require regular maintenance

Ultrasonic Cool Mist Humidifiers

This model hasn’t been around as long as evaporative cool mist humidifiers have, but they’re becoming increasingly popular. They work by using a diaphragm that vibrates at high-speeds and that helps to turn the water in its tank into a fine mist. These models don’t have filters, are generally quiet, and tend to use less energy. Let’s take a closer look at their pros and cons.


  • They’re quite effective
  • They’re energy-efficient
  • They’re quiet
  • They don’t require a lot of maintenance


  • They cost more than other humidifiers
  • They don’t work well for larger rooms

Consider Tank Capacity

Another thing to think about is how much water the humidifier holds in its tank. A bigger tank generally means that the unit can operate for longer periods, but it also may mean that the tank is difficult to refill. Therefore, the consumer is going to want to make sure that they choose a size that’s not too big as to be difficult to refill nor one that’s so small it doesn’t operate for a decent amount of time. 

Other Features To Seriously Think About

Okay, as we conclude this article, we think it’s a good idea to talk about some of the other features that you might want to think about before buying a new cool-mist humidifier. Not everyone will need a humidifier with all of the following features, but many of them make the humidifier easier to use or more effective, so let’s take a closer look at them before we conclude this article.

  • The cost of the humidifier
  • Whether it has a shut-off timer or not
  • Safety shutoff feature that turns the unit off
  • Adjustable water mist levels
  • Adjustable fan speeds
  • A 360-degree swiveling spout
  • A large tank refill hole
  • A humidistat
  • Built-in maintenance reminder alerts
